Installing ArcGIS Web Adaptor

ArcGIS Web Adaptor is provided as a setup program and is executed through a utility named Setup.exe. You can install ArcGIS Web Adaptor on its own using the steps provided here, or you can install silently using Windows Installer command line parameters.

Installation behavior and requirements

The ArcGIS Web Adaptor version must always match the version of its registered server site.

ArcGIS Web Adaptor can be installed side by side with other versions. You are not required to uninstall ArcGIS Web Adaptor to install ArcGIS Web Adaptor, and ArcGIS Web Adaptor is not an upgrade of previous releases.

Each ArcGIS Web Adaptor must have its own unique name; you cannot have two Web Adaptors with the same name on a single web server. If a naming conflict is detected during the installation, a warning message is displayed. You must uninstall the earlier version with the same name to resolve the conflict. Alternatively, you can change the name of one of the Web Adaptors to proceed with the installation.

Upgrade an earlier version of ArcGIS Web Adaptor

To upgrade an earlier version of ArcGIS Web Adaptor to 11.0, you must uninstall the earlier version, and install the 11.0 setup. During the 11.0 installation, you'll specify the same name as your earlier Web Adaptor. This guarantees your Web Adaptor URL will remain identical to the earlier version.

If a naming conflict is detected during the 11.0 installation, a warning message is displayed. You must uninstall the earlier version with the same name to perform the upgrade.

After installing 11.0, you must configure ArcGIS Web Adaptor with its corresponding server site.

Attempting to configure ArcGIS Web Adaptor so that the URL includes additional levels is not supported and may cause problems with client applications.

How to install ArcGIS Web Adaptor

  1. The ArcGIS Web Adaptor setup program should start automatically after the download is complete. If the setup does not start automatically, browse to the location of the downloaded setup files, and double-click Setup.exe.

  2. Review the terms and conditions of the master agreement. You must agree to the terms to proceed.

  3. Choose a website for the Web Adaptor. Available websites are listed as <website name (port)>. If you don't see the Select website dialog box, this means you only have one website. If only one website is found on your machine, ArcGIS Web Adaptor is automatically placed on that website without displaying the Select website dialog box.

  4. Type the name of the Web Adaptor. The default value is arcgis. This instance name cannot contain spaces.


    A message will display if a virtual directory with the same name as the Web Adaptor already exists in the selected website. Click OK to close the message, and provide a different name for the Web Adaptor.

  5. To complete the installation, follow the directions on the screen.

The Web Adaptor configuration page appears after the installation is complete. You are now ready to Configure ArcGIS Web Adaptor for use with your server.
